An evaporation plate for ice making machines is disclosed. This evaporation plate has a desired serpentine evaporation passage formed by an integration of two panels into a single plate, thus being free from a conventional separate serpentine evaporation tube. This is, the evaporation plate is formed by an integration of an upper panel, having a desired refrigerant channel formed on the panel through a pressing process, with a flat lower panel through a thermocompression bonding process into a single plate having a desired refrigerant passage formed by the channel. Since the evaporation plate is free from a conventional separate evaporation tube, it improves heat conductivity of refrigerant to a desired high level and is almost completely free from leakage of refrigerant. This evaporation plate also has a simple construction, and so it is automatically produced in commercial quantity at low production cost. The evaporation plate is preferably used in a conventional ice making machine while being integrated with an ice making cell plate.
